Description
式(6)および式(7)において、alf_block_xとalf_block_yは、それぞれ、i番目のALFブロックが横方向と縦方向に何番目であるかを示している。i番目のALFブロックの左上の画素の位置は、alf_block_xとalf_block_yのそれぞれに、alf_block_sizeを掛けた位置となる。すなわち、横方向は16×alf_block_xとなり、縦方向は16×alf_block_yとなる。従って、i番目のALFブロックの領域は、左上のその画素からalf_block_size×alf_block_sizeの範囲となる。 In the equations (6) and (7), alf_block_x and alf_block_y respectively indicate the number of the i-th ALF block in the horizontal direction and the vertical direction. position of the top left pixel of the i-th ALF blocks, each of alf_block_x and alf _Block_y, the position multiplied by Alf_block_size. That is, the horizontal direction is 16 × alf_block_x, and the vertical direction is 16 × alf_block_y. Therefore, the area of the i-th ALF block is in the range of alf_block_size × alf_block_size from the pixel at the upper left.
[ブロックサイズの更新]
さらに、ALFブロックサイズを更新するようにしてもよい。例えば、図22Aに示されるフレーム420のように、同一のテクスチャよりなる横長の領域が存在する場合、図22Bに示されるように、それぞれが正方形のALFブロック421では、いずれのALFブロックも複数のテクスチャを含むことになり、フィルタ処理の効果が低減してしまう恐れがあった。
[Update block size]
Furthermore, the ALF block size may be updated. For example, like the
そこで、制御情報生成部が、図22Cに示されるように、テクスチャの構造等、画像の内容に合わせて、ALFブロックサイズを更新するようにしてもよい。図22Cの例の場合、ALFブロック422は、それぞれが、テクスチャの構造に合わせて横長の長方形に設定されている。このようにすることにより、画像符号化装置または画像復号装置は、より良いフィルタ結果を得られるように、局所的なフィルタ処理の制御を行うことができる。
Therefore, as shown in FIG. 22C, the control information generation unit may update the ALF block size in accordance with the content of the image, such as the structure of the texture. In the example of FIG. 22C , each of the
